Imaging at micrometer resolution using a Blu-ray drive

Serious things have happened in our country (the U.K.) overnight, so we thought we would cheer ourselves up by imaging a lithographically fabricated familiar figure. The Jolly Wrencher was patterned with direct write laser lithography, which can reach a resolution of better that 1 um, and of course it is similarly imaged with our scanning laser beam, with similar resolution. The total width of the Wrencher field is 125 um, which is just less than the minimum track width you can order from OSH Park (150 um).

It is pretty small, enjoy!

And here is a more standard microscopy image (using a x5 objective), showing the full pattern that we fabricated. The metal film that has been patterned is gold (100 nm) with a chromium adhesion layer (10 nm) to a polished sapphire substrate.

This is RIDICULOUSLY cool!!!
